I'm not defending Nazis and I think you can see that. My take is that its harmful to label and then use that label to dehumanize a group of people. That type of behavior brings a witch hunt in the best case and genocide in the worst.
Were some people "objectively" witches during the Salem witch hunts? Were others "objectively" communist during the Red Scare? Many victims of the holocaust were objectively Jews.
I can see where you're coming from and understand why you feel that way: bigotry damages the world. We don't have to agree that calling people Nazis dehumanizes them and that dehumanizing people is harmful, that's fine. Peace be with you.
